'n' can be any number, but when applied to (2n + 4), n = 2.5
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
3n + 2n = 25 5n = 25 n = 5
You cannot, because there is no solution.5 is not a factor of 144. Therefore 5 is not a factor of (3n + 9)! / (2n + 4)!Therefore (3n + 9) - (2n + 4) < 5n < 0.Also, 2n + 4 must be non-negative.ie 2n >= -4 or n >= -2.So the only possible values for n are -1 and -2.But n = -1 gives 6!/2! = 720/2 = 360while n = -2 gives 3!/0! = 6

2n plus 5 n would be 7n and its impossible to solve the value of n.
4(n + 2)(2n + 5)
'n' can be any number, but when applied to (2n + 4), n = 2.5
-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:
Solve for n. 6 = 1 - 2n + 5 6 = 6 - 2n 2n = 0 n = 0 Check it. 6 = 1 - 0 + 5 It checks.
3n + 2n = 25 5n = 25 n = 5

n = 1
n + 2 = 5, solve for n.n = 5 - 2n = 3
10n = 7n + 4 + 2n so 10n = 9n + 4 Subtract 9n from both sides: n = 4
